My family didn't believe in spankings, so I never got one until I was in my teens and then it was at my 16th birthday party, hosted by my girl cousin, and she invited several other cousins over ... so it was pretty much family.
We played the normal teen games, including some kissing games, andthen the party host, after about an hour, said "It's time for cake and ice cream" and started singing "Happy Birthday".
When we finished singing, she said, "I guess it's time for Sandy's birthday spanking," to which I said "No", and she responded, "But it's a family tradition."
They all sorta pounced on me, put me across a chair, and then I felt my tennis shorts (elastic banded) being slid down along with my panties and the first swat hitting my bare butt. I scream, told them to stop, but the all said they had to have a turn and If I protested, I would lose my blouse too. I didn't believe them ... sure enough, my host pulled my blouse off over my head (along with the help of other cousins) and then unsnapped my bra ... leaving me naked.
I was so totally embarrassed ... but then my host continued the spanking ... right up to No. 16, then passed me on to a boy cousin who was seated on another chair ... he didn't slap me hard, but it did sting.
While this was going on, my host said, "Well, what's good for the goose is good for everyone else" to which everyone laughed, but I didn't see what was going on ... while I was being spanked, all the others got unddressed ... everyone was naked. What a sight, eight cousins, mixed company, all naked.
They passmed me around and everyone took their turn spanking me ... and finally the host said, "Well, it's Sandy's turn"
I didn't know what she mean until she said I should sit down on the chair, and each of my cousings laid across my lap and received a spanking. My cousin even gave me a table tennis paddle (she was afraid my hand would get sore, I think) and I gave each of my cousins a spanking.
When it was all done, there were nine people with somewhat red butts, but no one complained as we went into the kitchen for ice cream and cake. We ate while naked, talked afterward about the party, some playfully swatted my butt, or any butt available, during the afternoon.
Finally, we all got dressed and went home.
I didn't realize this family traditions, but it was somewhat of a secret society among the teen members of the family ... the 16th birthday resulted in a spanking party .... and teens were invited until they graduated from high school or went off to college.
I had my share of spankings at these future parties, gave a number of spankings to 16-year-olds who were just as embarrassed, just as surprised and just as initiated into the family tradition as I was.
As I said, I was totally embarrassed at the time, but even toward the end of the party, I was totally relaxed and got a whole new outlook on spanking, nudity and the more adult way of life.
